TO ALL WHOM ITMAY CONCERN: n y, n

Be itvknown thatl I, DAVIDYWHISLEMof Union township,'iu the county of Hancock, and State of Ohio,

have invented certain new and useful Improvements in Ditehing-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which fornita partof this,specificat ion. which make a part of this speoiication l i A 'Y Figure 1 represents a plan view `of muyV ditching-plough Figure 2 is ,la side elevation ofthe same.

The letter Adesignates the beam, and B a cross-bar, to which the axles of wheels C C are attached by staples. The cross-bar B is supported by the block e, which rests on the beam A.4 F represent two metal plates, one being fastened to each Side of the standard,I and thereby hiding the standard from view. The plates F extend beyond the rear and of the plough-beam, and rest against the cross-piece G, into which the ploughbeam is niortised. To hold the plates Fin position, the straps m m and n n are provided; the straps m m conning the ends of the said plates to cross-piece G, and' the straps n n conningthe centre of the plates to cross' bar B.' The plates 'F occupy nearly a vertical position,gand each is furnished with the metal wing Hwhich ,decline at small angle from plates F.' The wings H are supported at their lower ends by the shovel K, to which they are fastened, and near their upper ends they rest on the iron bars, the said bars being fastened tothe lower side of cross-piece Gby metal bands. The shovel K is held in a firm position by' an iron stripmonpeach'side, the upper ends of said strips being secured by staples to cross-bar B. The under side ofplough or shovel K should be scoopedl out as.represonted in fig. 2.4 lz' z' represent twoiron rods, whichbind cross-bar B to beam A. '.l represents a small platform, whicli'is made adjustable, by being hinged at one end to beam A, while the oppositeend may be raised or lowered by the screw- L. The platformT will be held inthe required position by the springs t. The object of this platform is to regulate thedepth ofthe plnghrinothe soil. To the bottom of platform T is secured, in `a. vertical position, the knife P, for the purpose-of cutting roots near the surface of the earth. Vf designates'a coulter, lplacedin front of the standardffor the purpose of eutti'ngproots. The object of the wheel-s C'is to' facilitate the removing o f my ditcher by reversing it, so that the wheels will res't on the ground. v l A 'Having thus described my invention, what I claim, 'and desire to secure by Letters Patentis-' l 1. The hinged platform` ',l, for regulating the depth of thebfurrowor ditch, substantially as'described. 2. In combination with the above, I claim screw l. and springs t, substantiallyas set forth. 3. I claim axle B, wheels C C, beam A', platform T,scr ew z, springs t, and vertical knife P, all combined and arranged as and for the purpose set forth. anddescribed.

In testimony that Iclaim the foregoing asluy own, I alix ,my signature in presence oftwo witnesses'.
